Juvenile Idiopathic Arthritis: fixed therapy vs invisalign®

Introduction: Juvenile Idiopathic Arthritis (JIA) is a type of rheumatoid arthritis, a chronic disease of joint inflammation that ap-pears before the age of 16 and persists for at least 6 consecutive weeks. This is not a single disease, but a syndrome with unknown etiological differences. The primary objective of the corrective orthodontic function will therefore be to stimulate the mandibular aesthetic development by restoring a vectorial age of growth. Following the first phase achieved with the use of the de-vices listed above if passed to the phase for alignment. It is important to specify that orthodontic therapy is complementary to systemic therapy, therefore pending the period of application of orthodontic appliances, the patient must continue the treatment with the drugs prescribed by the specialist and deemed most suitable for the form of their disease. Objective: the aim of this work is to evaluate the advantages of using the “Invisalign" technique over traditional fixed multi-bracket therapy for the purpose of the first phase of functional equipment in patients with JIA clinically healed or with little TMJ compromise. Methods: this study was conducted on a group of JIA patients in the orthognadontics ward of the Ospedale Maggiore Policlinico IRCCS Ca' Granda treated with “Invisalign" and with fixed multibrackets therapy. Results: we have found the advantages of “Invisalign" therapy: patient comfort, greater aesthetics, easier home oral hygiene, absence of urgencies, no compromise on diet. Furthermore, in JIA patients the main advantage is the possibility of temporarily suspending therapy in the event of the reappearance of pains and the use of the mask as a hold and bite. Conclusions: “Invisalign" therapy in JIA patients can be considered an excellent alternative to multibrackets therapy.
